西安華恒變送器制造商已經(jīng)開發(fā)出傳感器和智能電路板這兩項(xiàng)核心技術(shù)。 不僅掌握了所有產(chǎn)品的所有核心組件技術(shù)，而且工業(yè)自動(dòng)變送器制造商的精度也在不斷提高，從0.2提高到0.1。 通過擴(kuò)展精通的核心技術(shù)，它還可以改變其他測(cè)量流量和溫度的產(chǎn)品,華恒儀表-液位變送器廠家生產(chǎn)的3151智能型液位變送器在立足西北工業(yè)動(dòng)化工業(yè)生產(chǎn)的過程中相對(duì)重要的儀器儀表.所測(cè)液體靜壓與該液體高度成正比的原理，采用擴(kuò)散硅或陶瓷敏感元件的壓阻效應(yīng)，將靜壓轉(zhuǎn)成電信號(hào)。經(jīng)過溫度補(bǔ)償和線性校正，轉(zhuǎn)換成4-20mADC標(biāo)準(zhǔn)電流信號(hào)輸出。
Xi'an Huaheng transmitter manufacturer has developed two core technologies, sensor and intelligent circuit board. Not only master all core component technologies of all products, but also the accuracy of industrial automatic transmitter manufacturers is constantly improving, from 0.2 to 0.1. By expanding its core expertise, it can also change other products that measure flow and temperature, 3151 intelligent liquid level transmitter produced by Huaheng instrument level transmitter manufacturer is relatively important instrument in the process of industrial production in Northwest China. The principle that the measured hydrostatic pressure is directly proportional to the liquid height is adopted. The hydrostatic pressure is converted into electrical signal by the piezoresistive effect of diffused silicon or ceramic sensitive elements. After temperature compensation and linear correction, it is converted into 4-20madc standard current signal output.
3151智能電子式磁翻板液位計(jì)，對(duì)于經(jīng)常在罐區(qū)工作的朋友來說太普通不過了，3151智能電子式磁翻板液位計(jì)由于其結(jié)構(gòu)簡單易維護(hù)，測(cè)量數(shù)據(jù)直觀受到廣大罐區(qū)用戶的喜愛，對(duì)于他們來說這是一種太熟悉不過的液位測(cè)量儀表了。我們?cè)诓簧俟镜漠a(chǎn)品介紹中注意到他們對(duì)于磁翻板是否存在盲區(qū)的判定給用戶帶來的困惑，華恒儀表做出部分解釋
3151 intelligent electronic magnetic flap liquid level meter is too common for the friends who often work in the tank farm. Because of its simple structure and easy maintenance, the measurement data of 3151 intelligent electronic magnetic flap liquid level meter is loved by the majority of tank farm users. For them, it is a kind of liquid level measuring instrument that they are too familiar with. In the product introduction of many companies, we noticed that they were confused about whether there was blind area in the magnetic flap, and Hua Heng instrument made some explanations
我們認(rèn)為無論是什么產(chǎn)品都不可能是十全十美的，而儀表產(chǎn)品設(shè)計(jì)和使用中出現(xiàn)盲區(qū)也是一個(gè)非常正常的現(xiàn)象。只要我們?cè)谑褂眠^程中能夠予以正確的認(rèn)識(shí)，并加以重視，就能夠有效地規(guī)避這些問題帶來的影響。那么，用戶在遇到這些問題應(yīng)該如何解決，如何避免這類問題的發(fā)生呢？潤中科技的技術(shù)人員帶來分析其產(chǎn)生的原因及規(guī)避的方法，希望給大家的工作帶來幫助。
We think that no matter what product is, it is impossible to be perfect, and it is also a very normal phenomenon that there is a blind area in the design and use of instrument products. As long as we can correctly understand and pay attention to it in the process of use, we can effectively avoid the impact of these problems. So, how to solve these problems and how to avoid them? The technicians of Runzhong science and Technology Co., Ltd. will analyze the causes and avoid the methods, hoping to bring help to everyone's work.
我們*先分析3151智能電子式磁翻板液位計(jì)為何存在盲區(qū)，3151智能電子式磁翻板液位計(jì)盲區(qū)影響液位測(cè)量嗎？ 我們知道磁翻板測(cè)量管內(nèi)部的浮子本身是必須有長度的，即使再短也有長度，那么當(dāng)液位為零或者接近零的時(shí)候，為了達(dá)到精確測(cè)量的效果，那么浮子肯定是以零液位起始上浮測(cè)量，所以盲區(qū)必須考慮到零液位以下浮子的長度。這就解釋了為什么3151智能電子式磁翻板液位計(jì)存在盲區(qū)，而這些盲區(qū)距離都是固定的，這是由于產(chǎn)品本身結(jié)構(gòu)的原因造成的。對(duì)于3151智能電子式磁翻板液位計(jì)具體到以下面兩種情況，有著不同計(jì)算液位的方法：
We * first analyze why there is a blind area in the 3151 intelligent electronic magnetic flap liquid level meter. Does the blind area of the 3151 intelligent electronic magnetic flap liquid level meter affect the liquid level measurement? We know that the floater inside the magnetic flap measuring tube must have a length, even if it is short, so when the liquid level is zero or close to zero, in order to achieve the effect of accurate measurement, the floater must float up from the zero liquid level, so the length of the floater below the zero liquid level must be considered in the blind area. This explains why there are blind areas in 3151 intelligent electronic magnetic flap liquid level gauge, and the distance between these blind areas is fixed, which is caused by the structure of the product itself. For the 3151 intelligent electronic magnetic flap liquid level meter, there are different methods to calculate the liquid level in the following two cases:
一、如果3151智能電子式磁翻板液位計(jì)罐體的底端下面空間足以滿足盲區(qū)部分的距離，在設(shè)計(jì)選型的時(shí)候，法蘭安裝的時(shí)候肯定是在罐體底端與頂端之間，這時(shí)候計(jì)算液位的時(shí)候就要考慮盲區(qū)。
1、 If the space under the bottom end of 3151 intelligent electronic magnetic flap liquid level gauge tank body is enough to meet the distance of the blind area, during the design and selection, the flange installation must be between the bottom end and the top end of the tank body. At this time, the blind area should be considered when calculating the liquid level.
二、罐體的底端下面空間足以滿足盲區(qū)部分的距離，那么這時(shí)候3151智能電子式磁翻板液位計(jì)兩法蘭中心之間的距離就是滿液位距離，不用考慮盲區(qū)。
2、 The space below the bottom of the tank body is enough to meet the distance of the blind area. At this time, the distance between the two flange centers of the 3151 intelligent electronic magnetic flap liquid level gauge is the full liquid level distance, without considering the blind area.
以上兩種情況是針對(duì)側(cè)裝3151智能電子式磁翻板液位計(jì)的，而如果用戶采用的是頂裝3151智能電子式磁翻板液位計(jì)，那么3151智能電子式磁翻板液位計(jì)就不存在盲區(qū)問題了。
The above two situations are aimed at the side mounted 3151 intelligent electronic magnetic flap liquid level meter. If the user adopts the top mounted 3151 intelligent electronic magnetic flap liquid level meter, there is no blind area problem in the 3151 intelligent electronic magnetic flap liquid level meter.
